Problems solved by technology

It can be seen that the existing devices cannot simulate the explosion environment of explosives under normal use conditions, so as to objectively reflect the content of toxic gases produced after explosive explosions, and cannot meet the test conditions for large-dose, large-diameter charges of explosives without detonator sensitivity.

Abstract

The invention discloses a test method for a toxic gas explosion box test device, which comprises an explosion box, a mixing mechanism, a gas collection mechanism and an exhaust mechanism; the explosion box has an explosion chamber, and the inside of the explosion chamber is provided with The mortar of the sample; the mixing mechanism includes a mixing pipeline, both ends of the mixing pipeline are connected to the explosion chamber, and an air compressor and a pneumatic valve are connected to the mixing pipeline; the gas collection mechanism includes a collection pipeline and an exhaust A valve, one end of the collection pipeline communicates with the mixing pipeline. The invention makes the explosive explode under normal pressure through the cooperation of the mixing mechanism, the gas collection mechanism and the exhaust mechanism. The test charge can reach 500g TNT equivalent, and the charge diameter can reach 100mm, which fills the domestic explosive toxic gas generation test. The experiment using emulsion explosives provides a scientific method for testing the toxic gas content of explosives without detonator sensitivity.

Description

technical field [0001] The invention relates to the technical field of explosive toxic gas testing equipment, in particular to a testing method for a toxic gas explosion box testing device. Background technique [0002] The toxic gas content of existing industrial explosives tested in China is less than 130g, and the diameter of the charge is not greater than 45mm. It is measured after vacuuming in the cartridge, and the analysis of carbon monoxide and nitrogen oxides is carried out by chemical analysis methods. It can be seen that the existing devices cannot simulate the explosion environment of explosives under normal use conditions, thereby objectively reflecting the content of toxic gases produced after explosive explosions, and cannot meet the test conditions for large-dose, large-diameter charges of explosives without detonator sensitivity. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least...
